Puerto Rico: AM Radio makes a comeback post-hurricane

(Source: Columbia Journalism Review)

ON SEPTEMBER 19, 2017—the day before Hurricane Maria made landfall in Puerto Rico—the evening news team at WORA-TV in the coastal city of Mayagüez broadcast its final program before shutting down the station ahead of the storm.

“If Maria was going to be the monster everyone was predicting,” says Carolina Rodriguez Plaza, the news team’s production manager, “we knew the power could be cut off for a long time. We decided to shut down the station and send everyone home.”

Plaza told her team of 12 reporters not to worry, their salaries would be paid during the downtime and their jobs would be waiting for them when broadcasting resumed. Plaza retreated to her parents’ home, where she spent the night of the hurricane watching updates about the storm on cable TV. Then, as happened in homes across Puerto Rico, the lights flickered and the power went out. Hurricane Maria’s 150-mile-per-hour winds toppled power lines and torrential rains grounded out the island’s power grid.

Desperate for news about the disaster befalling her island, Plaza turned on a battery-powered radio and found that a local radio station, WKJB 710 AM, was maintaining its broadcast. The station’s managers had learned a lesson about disaster preparedness in 1998, when Hurricane Georges blew down their radio antenna and cut off the power. Since then, staff had equipped the station with a backup power generator and a reinforced antenna that could withstand hurricane-force winds.

“Maria erased the world of journalism in Puerto Rico,” Plaza says. “It reemerged in a new form, with radio playing an important role.”[…]

Low-frequency World Heritage Grimeton Radio Station, SAQ, will transmit from Sweden on May 1 as participation in the European Route of Industrial Heritage’s “Work It Out” observance.

“As part of the event, we plan for the first SAQ transmission since 2016,” said Lars Kalland, SM6NM. The transmitter start-up will begin at 0930 UTC, with the transmission to follow on 17.2 kHz CW at 1000 UTC.

A live video stream of the event will be available. Kalland said no QSL cards will sent, nor will SAQ post a list of reports, but SAQ does invite brief listener reports via e-mail.

“We sincerely hope that all the SAQ transmission on 17.2 kHz will go as planned,” Kalland said. “But, as always, there is a reservation that the transmission [may be] cancelled on short notice.”

WTPF’s former site: A “Time Capsule from the 1940’s”

The distinct Art Deco style clearly defines the WPTF radio station as a 1940’s classic.

With rounded windows and curved edges, the building looks tiny on the outside, but cuts deep underground into a shelter that allowed announcers to broadcast through wars and hurricanes.

Today, it’s hidden behind tall shrubs, a chain-link fence, and a set of train tracks – it often goes unnoticed, a relic from a long past era of Raleigh history.

Decades ago, this station was staffed 24-hours a day, which means it provides amenities like a kitchen and shower. However, this enticing building has been closed to the public, mostly forgotten, for decades. Nearly 80 years old and sealed to most of the outside world, it harbors dust-coated secrets that time forgot, like a living time capsule.[…]

Many thanks to SWLing Post contributor, Moshe, for sharing the following video:

I uploaded this video I made in a rush, holding our baby in one hand and my smartphone in the other one…

The receiver is my Ben-Gal Verdi.

I caught the station by accident, while tuning to VOA 15580kHz to listen to Boarder Crossings.

Fantastic catch, Moshe! Thank you for sharing. I can’t tell you how many times in the past I played radio while also holding a baby in my arms. Always a challenge!

Listening to ARISS contacts last week

I get just as excited as my kids when I receive any communications from the International Space Station. This past week, we fit an ARISS contact fit into our hectic schedule during lunch break. I gave both of my kids a handheld radio and we all listened together as the ISS passed overhead.

Right on schedule, we heard NA1SS, but it sounded like they were struggling to make contact with KD2IFR at the Central Islip Union Free School District in Central Islip, NY.

I made a short video about one minute into the scheduled contact. I believe both parties were forced to move to their backup channel because we never heard an exchange–only NA1SS calling KD2IFR:

Still…we heard an astronaut live, so mission accomplished!

SWLing Post contributor, Mark Hirst, had much better luck last week monitoring an ARISS contact with King’s High School in Warwick, UK. Check out his excellent video:

Thanks for posting that video, Mark. By the way, I love your FT-817ND setup!

In fact, the King’s High School ARISS contact snagged some excellent publicity via the BBC.  Here’s an article via the Southgate ARC:

King’s High School ARISS contact on BBC TV

On April 19 student Eleanor Griffin led the live question and answer session between King’s High School (GB4KHS) and astronaut Ricky Arnold KE5DAU on the International Space Station (OR4ISS)

King’s High School strongly encourage their girls to develop their interests both inside and outside the classroom. This culture of empowerment led one of their girls to apply to ARISS Europe (Amateur Radio on the International Space Station) for a highly prestigious link-up to the International Space Station.

When Eleanor Griffin was selected to hold a space conversation with an astronaut, she was inspired to set up the Warwick Mars Project, for students across the Warwick Independent Schools Foundation, to further interest in Space Science. Eleanor says: “The moon landings belong to the generation of our grandparents, and the International Space Station to our parents. What will happen in our generation? Will Mankind travel to another planet?”

When asked what the incredible experience of the ISS contact had taught her Eleanor replied “Just do it! No one is going to stop you, if you just go and pursue your dreams, you really can do anything.”
